FEED-TABLE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 569,283, dated October13, 1896.

Application filed June 6, 1896. Serial No. 594,476- (NO model-l To (allwhom it may concern:

Be it known that I, SIGMUNDV.HUBER,a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented or discovered certain new and useful Improvements inFeed-Tables for Rollin g-WIills, of which improvements the following isa specification.

The invention described herein has for its object a construction offeed-table for rollingmills for the reduction of billets to merchant baror wire rod; and it consists, generally stated, in a construction orarrangement of delivery-rolls, receiving boxes or troughs, andinterposed mechanism between the receiving and delivery parts whereby anaxial rotation of the article being rolled may be effected while beingtransferred from the receiving to the delivery mechanism.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan View of my improved rolling-mill. Fig. 2 is asectional plan view, the plane of section being indicated by the line ofsection II II, Fig. 4... Fig. 3 is a sectional elevation, the plane ofsection being indicated by the line III III, Fig. 4; and Fig. 4 is atransverse sectional elevation, the plane of section being indicated bythe line IV IV, Fig. 3.

In the practice of my invention I arrange in front of a stand ofthree-high rolls a suitable framework or foundation, which supports theoperating parts of the feed mechanism. On this framework are securedmetal plates 1, 2, 3, A, 5, and 6, so arranged with reference to thepasses through the rolls as to form lateral guides for the article beingrolled as it is being received from the rolls. For example, the walls orplates 1 and 2 are arranged on opposite sides of the pass a of therolls, the plates 2 and 3 on opposite sides of the pass I), the plates 3and 4 on opposite sides of the double pass 0, the plates 4 and 5 onopposite sides of the double pass d, and the plates 5 and (5 on oppositesides of the double pass 6, as clearly shown in Fig. 4. Between thewalls or plates 1 and 2 are mounted the rollers 7 the shafts of saidrollers being mounted in the plates 1 and 2 and in outside bearings 8,and are provided at their outer ends with suitable bevel-pinions adaptedto intermesh with corresponding pinions on the driving-shaft 9. Theserollers are arranged and rotated in such direction as to feed the billetinto and through the pass a of the rolls. By suitablemechanism,preferably such as is described in an application of even dateherewith, the article is dropped down on the opposite side of the rollsand returned through a pass 1) between the middle and lower rolls.Between the walls 2 and 3 are arranged the receiving-rolls 10, which aremounted upon shafts 11, driven by the powershaft 12 through the mediumof suitable beveled gearing.

As shown in Fig 1, the wall 2 is countersunk at suitable intervals,forming a guide recess or groove for the vertical slides 13, which areconnected at their lower ends to rack-bars 14, adapted to intermesh withpinions 15 on the shafts 16. These vertical slides 13 are arrangedintermediate between the feed -rollers 12 and have attached theretodownwardly-inclined plates 17. \Vhen the slides are at their lowerposition, these inclines 17 are below the line of feed of the barpassing through the pass I), as shown in Fig. 4. After the article haspassed entirely out of the bite of the rolls the shaft 16 is rotated bymechanism hereinafter described, thereby raising the slides and withthem the inclines 17, so as to lift the article off the feed-rollers andabove the wall 3, which retains the articles on the inclines during theupward movement of the latter. As soon as the inclines pass above thewall the article will slide off of the inclines onto one or the other ofthe grooves in the feed-rollers 18, dependent upon which one of thepasses c c of the rolls the article is to be fed through.

In order to insure the article dropping into the proper groove of thefeed-rollers 18, brackets 19 are provided and detachably secured to oneof the walls 3 or 4, dependent upon which pass a or c is to be used. Asshown in Fig. 4, the brackets 19 are arranged over the pass 0, so thatthe article sliding from the inclines 17 will drop into the groove inthe feed-roller 18 in line with the pass 0.

If the article is to be fed through the pass 0, the brackets or bridges19 will be reversed, so as to cover the groove in the roll 18 in lineIOO with the pass 0 and form a practical continuation of the incline 17when the latter is raised. As shown in Figs. 1 and at, the feedrollers18 are formed on opposite sides of the gear-wheel 20, which is rotated,through the medium of suitable interposed idlers,by one of the shafts 11in such direction as to feed the article into the pass 0 or c. On theopposite side of the reducing-rolls the article is received by suitablemechanism and dropped down with a slight lateral movement, so as to bereceived through the pass d by the rollers 21, arranged on the shafts 11between the walls at and 5. The wall 4 is provided with guide-groovessimilar to those in the wall 3 for the reception of vertical slides 22,which are connected at their lower ends to rack-,

bars 23, adapted to intermesh with pinions 2% on the shaft 25. On theslides 22 are attached inclines 26 at such points that when the inclinesare at their lower position the inclines will be below the line ofmovement of an article passing through pass (Z, as clearly shown in Fig.4. As the article has been considerably reduced by the time it is actedon by the pass 61, and is therefore liable to bend and twist, it ispreferred to secure to the slides 22 retaining plates or blocks 27 insuch position upon the slides that when the latter are in their lowerposition the retaining-blocks will be just above a horizontal planepassing through the pass d of the reducing-rolls. These retaining-plateswill prevent any material vertical bending or twisting of the bar; butits lateral bending is prevented by means of horizontally-curved blocks28, attached by means of plates 29 to the walls 4 and 5 intermediate ofthe vertical. slides, as clearly shown in Figs. 2 and 4. After thearticle has passed out of groove (1 the slides 23 are raised, therebylifting the article,which is prevented from moving off the inclines 26by the vertical wall 5, until the inclines are above said wall,whereupon the article will slide off into one or the otherof the passese e, dependent upon the position of the bridges or brackets 30. Thesebridges or brackets are similar to the bridges or brackets 19 and aredesigned to insure the dropping of the article onto the feed-rollers 31in line with the proper pass 6 or e. As the article drops from theinclines it is received by feed-rollers 31, mounted on suitable shaftsand rotated, through suitable interposed gearing, by the power-shaft 32in such direction as to feed the article resting thereon into one or theother of the passes e e.

On the opposite side of the reducing-rolls the article is received bysuitable mechanism, lowered and shifted a short distance laterally, andfed into one or the other of the passes f.

On the rear ends of shafts 16 and 25 are secured gear-wheels 33 and 34,adapted to intermesh with a rack-bar 35, arranged in suitable guides atthe rear end of the feed-table and reciprocated back and forth withinsaid guides by means of a fluid-pressure cylinder 36, whose piston isconnected by the rod 37 to the rack-bar.

It is characteristic of my improved feedtable that the bar isautomatically received and returned to the reducing-rolls, the onlynon-automatic operation being the vertical so that it is possible foraseries of articles to be in the course of reduction in each of theseveral passes described simultaneously.

I claim herein as my invention- 1. A feed-table for rolling-mills havingin combination a series of delivery-rollers arranged in certain verticaland horizontal planes, a series of receiving-rollers arranged indifferent vertical and horizontal planes,

and mechanism for lifting an article from the receiving-rollers andshifting it laterally onto the deliveryrollers, substantially as setforth.

2. A feed-table for rolling-mills, havingin combination a series ofdelivery-rollers having two or more grooves, a series ofreceivingrollers arranged in a plane below the delivery-rollers, amechanism for lifting an article from the receiving-rollers anddepositing it on the delivery-rollers, and bridges for directing thearticle into the proper groove in the delivery-rollers, substantially asset forth.

3. A feed-table for rolling-mills, having in combination a series ofreceiving-rollers, a series of delivery-rollers arranged in a planeabove the receivin g-rollers, and vertical slides provided with platesdownwardly inclined toward the delivery-rollers, whereby an article maybe raised from the receiving-rollers and moved laterally onto thedelivery-rollers, substantially as set forth.

4:. A feed-table for rolling-mills, having in combination a series ofreceivingrollers, a series of delivery-rollers, vertical slides providedwith downwardly-inclined plates, and with retaining plates above theinclined plates, and curved blocks intermediate of the slides,substantially as set forth.

In testimony whereof I have hereunto set my hand.
